nRF52840, MQTT, TLS1.2

[Reto]

Dear Nordic,

What I want to do:

• Battery powered sensor network
• One gateway (BLE --> WLAN) with a serial-to-wifi chip connected to nRF52
• MQTT (IBM Bluemix --> CoAP is not supported)
• TLS1.2 (IBM Bluemix)
• Long range (Bluetooth 5), indoor and outdoor

So I guess I need a nRF52840. What is the best SDK to start with?

• nRF5 SDK for IoT?
• nRF5-SDK V13.0.0?
• Any good example around?

Thank you!

Unfortunately, we do not have support for IPSP router role, which you would need in the gateway.

See this for more information.

Thank you Petter. I am thinking of leaving this path and going with nRF52840 and Thread SDK, as it seems more supported by Nordic. In this case: I would not build the border router by myself (I would buy a 802.15.4 / Wifi / LAN boarder router). But Thread SDK does not support MQTT and I need MQTT (as I want to connect do IBM Watson IoT).

• But how long will it take until you support MQTT-SN (UDP) over Thread on nRF52840?
• I don't think I can use MQTT/TCP over Thread: right?

Thank you Petter! Reto
